To @ZZ whom t may concern Be it known that I, JOHN F. KELLY, a citizenof the United States, and a resident of Trenton, in the county of Mercerand State of New Jersey, have invented certain new and usefulImprovements in Water- Closet Bowls, of which the following is aspecification.

My present invention relates to the construction of water closet bowlsmade of porcelain or other similar material, the object being to providea closet which is silent in operation. l

It has been the aim for many years in this art to reduce the noiseattendant upon flushing the bowl by varying the manner of supplying thewater to the various parts and such efforts have met with more or lesssuccess in practice. Part of the noise comes from the jet holes in theiiushing rim as the air is suddenly forced out due to the sudden in-rushof water causing a' hissing sound and further noise is characterized bya gurgling sound as the level of the water in the well of the bowl dropslower than the lip in the uprising leg of the Siphon when lthe bowl isbeing washed out. By constructing a closet bowl in accordance with thisinvention such noises are reduced to a minimum and to a much greaterextent than has heretofore been accomplished.

The invention consists in the improved construction or formation ofwater closet bowl hereinafter more particularly described and thenspecified in the claims.

In the accompanying drawings, Figure 1 is a central longitudinal sectionthrough a water closet bowl constructed in accordance with thisinvention. Fig. 2 is a vertical cross-section taken on the irregularline 2-2 Fig. 1. The line of the cross-section where it passes throughthe top of the bowl is also indicated at 2-2 in Fig. 8. Fig. 3 is ahorizontal section taken on the line 3 3 Fig. 1.

1 indicates the closet bowl proper preferably formed as an integralporcelain structure and 2 the well containing a body of water the levelof which is controlled by a dam 3 connecting the upward leg 4: and thedownward leg 5 of a siphon discharge of any desired type.

6 indicates the inlet opening to which is connected the water supplypipes through which water is fed to the well 2 and the usual flushingrim 7 the flushing rim being provided with outlet jets or openings 8 asis well known in the art.

9 indicates the water reservoir compartment, the lower part of which islocated below the well 2 and communicates therewith by means of theusual siphon jet 10 so arranged, as usual, that when the iow of water isstarted the jet directs the water from the reservoir 9 up through thesiphon leg i and the contents of the well 2 are emptied through thesiphon discharge 4;, 5. The reservoir 9 extends upward between the upand down legs 4ll andl 5 of the siphon.

l1 and 12 indicate channels or passages formed at each side of the bowlat the rear and preferably as an integral part of the bowl. The channelor passage 11 connects the inlet 6 with the reservoir 9 and jet lOthrough a port 25 at the upper end of the channel and a port 16 at thelower end while the channel or passage 12 through a port 17 at the lowerend and port 26 at the upper end connects the reservoir 9 with theflushing rim 7. The port 26 establishes communication between thechannel 12 and a charnber 14 which in turn communicates with theflushing rim proper. The channels 11 and 12 and the ports 25 and 26 areseparated from each other at their upper ends by a partition 15 whichprevents the supply water entering the channel 12 direct from the inlet6 and causes all of the supply water delivered to the inlet to passfirst into the channel 11.

By this construction it is necessary forV the water in order to reachthe flushing rim to first pass through some part of the reservoircompartment Qwith which the Siphon jet l0 communicates and therefore itis the same water that passes into the reservoir that supplies the rim7. By causing the incoming water to first enter the reservoircompartment preferably below the jet, the reservoir acts as a mufiier tocheck the speed of the inrushing water and permits it to rise graduallyup the passage l2 and to the rim whereby it slowly forces the containedair in the rim through the openings 8 and prevents the air mixing withthe water as well as prevents the water compressing the air, both ofwhich cause the well known hissing noise.v When the air is allowed toescape easily as by the gradual rise of the water in the passage 12slowly forcing the air ahead of it the hissing sound is eliminated.

I also preferably form a transverse passage 18 in the lip 19 at theentrance to the upward leg 4: of the siphon which passage communicatespreferably with both the channels 11 and 12 and obtains water therefrom.The passage 18 may be provided in any desired manner by forming it inthe material of the bowl or by molding a metal or other pipe in thematerial or otherwise. A plurality of small outlet openings or jets 2Oare provided in the bottom of the passage 18 so that water in saidpassage will discharge or spray downwardly toward the bottom of the well2, the water from the openings preferably merging together and forming acurtain of water indicated at 21. If desired when separated openings areused they may be flared outwardly at the exits to more effectually mergethe individual streams. Then the transverse passage 18 is provided thesupply water, when admitted to the inlet, is fed to the passage 18 fromthe channel 11 and thence sprays downwardly or transversely across theopening to the siphon leg 4: so that when the level of the water hasfallen below the lip 19 due to the action of the jet 10 and Siphon 4, 5,any space which might otherwise occur between the water level and thelip 19 is sealed by the curtain 21 and the gurgling noise which usuallytakes place due to the dropping away of the water from the lip 19 isavoided. The curtain of water may be used either with or without theparticular manner of feeding the water to the rim hereinbeforedescribed.

It is thought theroperation of the closet is obvious. The water whenintroduced at the inlet 6 passes down the channel 11 and to thereservoir 9. Some of it is forced up through the jet 10 to assist insiphoning the well 2 while part of it rises up the channel 12 to theiiushing rim 7, gradually forcing the contained air ahead of it throughthe rim openings 8. At the same time, when the feature is incorporated,water enters the passage 18 and is discharged through the openings 20forming the curtain 21 across the entrance to the siphon leg 4; ashereto fore described.

It will be understood that the invention is not limited to the exactarrangement or details of construction as shown and described but thatvarious departures may be made from the same without departing from thespirit of the invention as expressed in the appended claims.

What I claim as my invention is 1. A water closet bowl provided with asiphon discharge and a transverse passage located at the entrance to thesiphon and adapted to discharge a curtain of water laterally across saidentrance when the closet is operated.

2. A siphon-jet. water-closet bowl provided with a transverse passageadapted to receive water and discharge it downwardly across the entranceto the siphon when the closet is operated.

3. A water closet bowl, provided with a well, a siphon discharge, atransverse passage located at the entrance to the siphon and adapted toreceive water and openings` in the bottom of said passage through whichthe water is discharged in a manner adapted to choke the air enteringthe siphon as the level of the water in the well lowers during theoperation of the closet.

4. A water closet bowl having a well, a reservoir below the well, aiiushing rim, a siphon discharge, a Siphon jet connecting said well andreservoir, a chamber adapted to supply water to said reservoir, meansadapted to supply water to said rim only after passing through saidreservoir and a transverse water passage communicating with said chamberand adapted to discharge water transversely across the entrance to thesiphon discharge as the level of the water in the well lowers during theoperation of the closet.

Signed at Trenton, in the county of Mercer and State of New Jersey, this7th day of July, A. D. 1915.
